BUTTON-SETTING MACHlNE.

SPECIFICATION forming part of Letters Patent No.31l,4=57, dated January27, 1885.

A plicnt-(n ad April 28, m4. (No model.)

To all whom it may concern:

Be it known that I, ERASTUS WOODWARD, of Somerville, county ofMiddlesex, State of Massachusetts, have invented an Improvement inButton-Setting Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention is an improvement on the machine represented inapplication No. 94,977, filed May 15, 1883, to which reference may behad, the object of my present invention being to adapt the said machineto the employment of strip nails or fastenings, as will be described,each nail or fastening being cut off and driven as wanted.

Figure 1 is a partial side elevation of a machine for attaching buttonsto shoes or other articles, sufficient in connection with the machinedescribed in the said application to enable my present invention to befully understood. Fig. 2 is a right-hand elevation of Fig. 1, part ofthe button-chute, the plate 27, and the anvil D being added. Fig. 3isatop View of Fig. 1, partially broken away at one side the shaft B tosave space on the drawings, and with the presser partially broken out.Fig. 4 shows in top and edge view the bracket to support the saidstrip-guide; Fig. 5, a detail in side elevation of the said nailstripguide; Fig. 6, enlarged details of the driver and nail-strip; Fig. 7, adetail of the transferrer, and Fig. 8 details of the upper end and innerside of the nail-guide detached.

In this application the bevel-gear B, shaft 13*, swinging frame B,set-screw B cam-hub D anvil-carrier D anvil D button chute or conductorE, link E radius-bar E pivoted at E block 16, bolt 15, slide E bolt 17,fastenertransferrer F, cam Gr, lever G, spring G, stop G projection e,engaged by lever G, driverbar 6, screw 26, bar N spring N slot N lever0, cam 0 gib p, screw 19, the under side, 27, of the button chute orconductor E, presserfoot or work-support P, its throat P presserbar Prigid frame A, spiral spring P, and spring I) are all as in the saidapplication, where the like parts are designated by like letters, thesaid parts in this present application being operated as in theapplication referred to.

To enable the present machine to use strip nails or fastenings, or nailsor fastenings connected together in a strip, I have removed the tackchute or conductor from the machine shown in the said application, andalso the centering device, and in place of the said parts I have added astrip-guide, 104, and a nail or fastening guide, 105, the latter beingattached to the bar N in place of the centering device. The strip-guide104, grooved at 106 for the reception of the nail or fastening strip sn,(shown in Fig. 6,) has a shank, 107, which enters a socket, 108, in abracket or plate, 109, bolted 6 to the swinging frame 13*. Thestrip-guide 104 at its front end has projecting from it a finger, 112,which passes under the nail-guide 105 (see Fig. 8) when the strip-guide104 is pushed forward by the transferrer F against the action of thespring 113, attached at one end to a pin, 114, on the strip-guide, and apin, 115, on the bracket 109, the said finger at suohtime acting againstthe side of the head of the endmost nail of the strip and forc- 7 5 ingits shank into the straight or vertical slot 122, made in the nail-guide105, (see Fig.

8,) and into position above the driver dr. The slot 122, into which theshank of the endmost nail is entered as described, is in line with themovement of the transferrer and tangential to a circle described fromthe center of motion of the strip-guide, so thatthe shoulder f 2 of thetransferrerF as it meets the finger 112 turns the strip-guide on itspivot 107, and at the same time pushes the endmost nail of thenail-strip into the slot 122, which results, it will be obvious, indrawing the nailstrip forward in the moving strip-guide, for the endmostnail is prevented from backward c movement with the strip-guide. Thedriver (11", attached by screw 26 to the driver-bar e, is a flat steelblade, preferably as wide as the head of the nail is long, and itcarries with it a cutter member, 108, which is adapted to 9 5 strikeagainst the nail-strip at its under side, as in Fig. '6, to sever thesaid strip by a blow between the said cutter member 103 and the loweredge of the steel cutter-plate 116, at-

tached to the nail-guide 105 such edge acting as the upper member of thecutting mechanism and entering one of the transverse grooves 101, whichit is preferred to make in the nail-strip, such groove not only servingto enable the nails to be separated uniformly and u nerrin gl y, butalso making a projection at the under side of the nail'head to enter theleather. The driver has a second projection, 118,which prevents the nailfrom moving or jumping horizontally when it is severed from the strip,and also acts to turn the outer end of the head into the material as thecutter 103 turns in the inner end of the nail.

iug carried into the groove 122 in thenailguide' 105. The shanks of thenails are marked 102, there being four nailsin the strip shown in Fig.6. The strip will be cut from sheet metal,and may be of any suitablelength.

. The nail-guide has at its top an opening, 117,

outthrough which the nail is driven when the upper end of the nailguideis thrown up against the under side of the workby the lever O, the workor material to which the button is to be attached resting on the presserI, and

between it and the plate 27, where it is held.

clamped, and the end of the nail driven through the material is clinchedto surround the shank of the button, as described in the saidapplication.

Herein I have shown the cutter member 103 aspart of the driver; but'itmight be an independent piece.

Instead of the particular nail-strip used,I may use any other suitableor well known strip, or, if desired, a strip in which the metal shanksare connected by means of paper.

The bracket 109 has a projection, 119, onwhich the head of the endmostnail of the strip rests as its shank is besta ntially as described.

2. 1 The anvi1, the nail-guide provided with the slots 122 and 117, andthe pivoted nailstrip guide 10st, provided with the finger 112,

com bin edwith the reciprocating slide or transferrer F, to operate thenai1-strip guide in one direction, substantially as described,

3. Ina machine for setting buttons, a nailguide and cutter-plate, 116,combined with a driver provided with a projecting cutter member, 103, tooperate substantially as described.

4. The driver provided with the cutter 103 and projection 118, to cutand act upon the ends of the head of a nail,.and embed the same into thematerial into which the nail is driven, substantially as described.

5. In a buttonsetting machine, a supportf6 P, for the material uponwhich the button is to be attached, a button conductor or chute,audanvil,- combined with the movable nailstrip guide, and driver andcutter working from below the said support and acting to cut a nail fromthe strip and drive'it into thema-- terial and'through the eye of thebutton, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two sub- 7 scribing witnesses.
